As several witnessed described on their social media accounts, airline officials originally announced that they needed four people to voluntarily give up seats so that United employees, who needed to be in Louisville, could board the plane.

They offered $800 to the passengers, however, when nobody offered, the staff selected four people — including the 69-year-old doctor, who told them he needed to make the flight to see some patients at his hospital the next day.

Police officers responded by grabbing the doctor, which caused him to slam his head against the armrest, and dragging him off the like a rag doll as blood oozed from his wounds.

It was a horrific video, but for some insane reason, it made O’Reilly chuckle.

“I shouldn’t be laughing, but it’s just so bizarre,” the embattled Fox host admitted aloud to the correspondent as he played the video.

A particular video making rounds on the internet shows the passenger with blood dripping down his face, repeatedly saying, “Just kill me” and “I want to go home.”

“They had to get some United Airlines personnel from Chicago to Louisville ... they had to get them there and so they asked for volunteers, and obviously, this guy didn't volunteer,” O’Reilly continued his depraved commentary on the United incident, still chuckling.
